The RCD is non-sealable and non-adjustable — the trip current and delay are factory-set. The 100 A rating holds only up to 40 °C ambient. Above that, the device must be derated: 93 A at 45 °C, 90 A at 50 °C, 87 A at 55 °C, 85 A at 60 °C, 83 A at 65 °C, and 80 A at 70 °C. The RCD withstands a surge current of 1 kA and a surge voltage of 4 kV. The rated fault current is 300 mA, non-adjustable. The device is instantaneous (no time delay), so it trips within milliseconds of a fault exceeding the threshold. It includes a protection function against false tripping, which helps avoid nuisance trips from transient surges.","metaTitle":"Siemens SENTRON 5SM2647-6 RCD, 4-pole, 100 A, 300 mA, Type A","metaDescription":"Siemens SENTRON 5SM2647-6 4-pole instantaneous RCD, 100 A rated current, 300 mA Type A, 50 Hz.
